The proliferation of online gambling platforms has heightened concerns over their potential to intensify problematic gambling behaviors. While previous research has examined various risk factors, the influence of prior online gaming experience on gambling transitions remains underexplored. This study investigates whether and how engagement with online gaming facilitates the migration from offline to online gambling.

This study determined the effects of message framing on helping behavior as a function of age in preschool and early school-age children. After validating the instrument used in a preliminary study, the researchers conducted a repeated-measures ANOVA of the responses of 90 children aged 5, 6, and 7 years. The results showed that, first, perceived importance and behavioral intention to help tended to increase with age.

New evidence suggests that industrial areas may have a negative impact on the chronic respiratory disease burden among residents who live more than 10 km away compared to residents who live within at least 5 km. The main cause of air pollution in factories was found to be benzene, and its regional relevance was confirmed. This is the result of many studies confirming that benzene is a substance that directly affects the respiratory system, and we aim to maintain continuous observation in the future.

SCORring atopic dermatitis (SCORAD) is widely used to assess the severity of atopic eczema, but score systems based on the entire body may be limited in effective monitoring and intervention. It is crucial to monitor moisture levels in each affected body part, but empirical research is still lacking. The objective of this study was to analyze the levels of stratum corneum hydration (SCH) and transepidermal water loss (TEWL) in atopic dermatitis (AD) patients, focusing on the presence and location of atopic lesions at different body sites.

Since automobiles are the primary means of transportation in modern society, the assessment of health effects from acute and chronic exposure to pollutants in automobiles is crucial. In this study, the concentration of volatile organic compounds (VOCs), carbonyl compounds, and odor-including substances in newly manufactured automobiles were analyzed, and exposure factors reflecting automobile user characteristics were selected for health risk assessment. Toluene exhibited the highest concentration (203.

Article Synopsis
  • Surgical stabilization of rib fractures (SSRF) is effective for flail chest patients, but hardware failure (HF) of implanted plates may occur, prompting this study to explore its clinical characteristics and factors involved.
  • Among 728 patients who underwent SSRF, 10.9% experienced HF, primarily screw loosening, with a mean age of 56.5 years; the majority of these patients were men.
  • Reoperations for plate removal happened in 26.3% of HF cases, primarily in younger patients, indicating a need for more research to identify risk factors associated with SSRF failure.

Background: Splenic arterial embolization (SAE) is an effective intervention for the management of arterial hemorrhage asso-ciated with blunt splenic injury. However, its role and clinical outcomes in pediatric and adolescent patients are unclear. The aim of this study is to assess the role and the clinical outcomes of SAE for blunt splenic injuries in pediatric and adolescent trauma patients.

Background: In patients with severe trauma, the diagnosis of acute kidney injury (AKI) is important because it is a predictive factor for poor prognosis and can affect patient care. The diagnosis and staging of AKI are based on change in serum creatinine (SCr) levels from baseline. However, baseline creatinine levels in patients with traumatic injuries are often unknown, making the diagnosis of AKI in trauma patients difficult.

Purpose: The scoring system for traumatic liver injury (SSTLI) was developed in 2015 to predict mortality in patients with polytraumatic liver injury. This study aimed to validate the SSTLI as a prognostic factor in patients with polytrauma and liver injury through a generalized estimating equation analysis.

Methods: The medical records of 521 patients with traumatic liver injury from January 2015 to December 2019 were reviewed.

Particulate matter has been increasing worldwide causing air pollution and serious health hazards. Owing to increased time spent indoors and lifestyle changes, assessing indoor air quality has become crucial. This study investigated the effect of watering and drought and illumination conditions (constant light, light/dark cycle, and constant dark) on particulate matter2.

Purpose: We aimed to assess the clinical efficacy of transcatheter arterial embolization (TAE) for treating hemothorax caused by chest trauma.

Materials And Methods: Between 2015 and 2019, 68 patients (56 male; mean age, 58.2 years) were transferred to our interventional unit for selective TAE to treat thoracic bleeding.

Article Synopsis
  • * Data from a trauma database was analyzed, including 192 patients, revealing that a median DTE time of 150 minutes was associated with higher mortality rates in the first 24 hours and overall, identifying DTE time as a risk factor for mortality.
  • * The research concluded that shorter DTE times led to better survival rates and clinical outcomes, emphasizing the importance of reducing DTE times to improve results for patients undergoing TAE for pelvic fractures.

It has been recognized that -Coumaric acid (-CA) has protective effects as an antioxidant, anti-inflammatory agent. A sensitive and efficient Liquid Chromatography-Mass Spectrometry (LC-MS) method for maximum determination of -CA in human plasma has been established using Ultra-performance liquid Chromatography-tandem mass Spectrometry (UPLC-MS/MS). This study provides the developed analysis of -CA extracted from in Taeniam (BC) to examine the improvement of the treatment -CA, IGF-1 and Osteocalcin level in human children which are important factors on the growth of children's height through Pharmacokinetics/Pharmacodynamics (PK/PD) model.

Purpose: To evaluate the clinical outcomes of fluoroscopic primary posterior urethral realignment (PPUR) for complete posterior urethral disruption (PUD) accompanied by complex pelvic fractures.

Materials And Methods: Data from 15 male patients (median age, 58 years; range, 32-76 years) with traumatic PUD treated with fluoroscopic PPUR between 2016 and 2019 at a regional trauma center were retrospectively analyzed. The technical success (continuity of the ruptured urethra in PUD by Foley catheter placement) rate of fluoroscopic PPUR, trauma mechanism, concurrent embolization for pelvic arterial hemorrhage, time from the hospital visit to the start of the procedure, procedure time, Foley catheterization duration, and delayed complications were investigated.

Article Synopsis
  • Transarterial embolisation (TAE) is a procedure used to control bleeding from pelvic fractures, but its impact on patient survival and outcomes was unclear before this study.
  • The researchers analyzed data from trauma patients treated between November 2015 and December 2019 and created a propensity score to compare survival rates at 28 days between those who received TAE and those who did not.
  • Results showed that TAE significantly improved 28-day survival rates, with 93.9% of patients treated with TAE surviving compared to 86.2% of those without it, indicating that TAE should be considered for severely injured patients with pelvic fractures.

The objective of this study was to estimate the concentrations of indoor air pollutants in unregulated public transport means in Korea and to determine the factors affecting the air quality as well as to assess the harmful effects of indoor air pollutants on the health of passengers. The correlation between particulate matter (PM) and number of passengers on intra-city buses, express buses, town shuttle buses, or rural buses was insignificant whether it was during rush hours or non-rush hours. In regard to PM on express buses, there was no case where the standard limit was exceeded during the winter and summer seasons.

The objective of this study was to investigate the concentration distribution of indoor air pollutants in taxis and ships (passengers) which are frequently used for public transportation and recreational activities in South Korea. In addition, it aimed to assess air quality factors to establish and evaluate the health risks of exposure to polluted indoor air. Particulate matter (PM) concentrations were not affected by the number of passengers, time of day, and driving characteristics because there were only a few passengers (2 to 4 people) and the space was confined.
